Lithium-ion and lithium-polymer are getting more popular in modern consumer electronics, LiPol manufacturers offer both lithium-ion batteries and lithium-polymer batteries. 

The most significant difference between lithium-ion and lithium-polymer batteries is the chemical electrolyte between their positive and negative electrodes. 

In Li-Po batteries, it isn’t a liquid. Instead, Li-Po technology uses one of three forms: a dry solid, which was largely phased out during the prototype years of lithium polymer batteries; a porous chemical compound; or, a gel-like electrolyte. The most popular among these is the last one, which is the type of battery you’ll find in newer laptop computers and electric cars. 

Lithium-polymer batteries are generally robust and flexible, especially when it comes to the size and shape of their build. They are also lightweight and have a lower chance of suffering from leaking electrolytes. But lithium-polymer batteries aren’t perfect either: they are significantly more costly to manufacture, and they do not have the same energy density (amount of power that can be stored) or lifespan as a lithium-ion.

“Lithium-ion batteries are incredibly efficient. They stuff freakish amounts of energy in a tiny package.” 

Typically, the advantage of a lithium-ion battery is high power density, lack of what’s called the memory effect (when batteries become harder to charge over time), and their significantly lower cost than lithium-polymer.  lithium-ion batteries are inherently unstable, suffer from aging, and are potentially dangerous. If the battery that separates the positive and negative electrodes is ever breached, the chemical reaction can cause combustion (fire). As Li-ion batteries have become more popular in consumer electronics, businesses have tried to lower costs by cutting corners. While quality batteries are perfectly safe, you should always be careful when buying no-name brands.

Meet Your Different Needs by Assembling the Battery in Series and Parallel.

The Max Discharge Current of Lithium-ion Battery LP21700:

-20°C ~ 10°C: 0.5C (2,400mA)
10°C ~ 25C°: 3.0C (14, 400mA)
25°C ~ 55°C: 1.5C (7,200mA)

The relationship between working temperature and the discharge performance of a Lithium-ion Battery LP21700, such as the 4800mAh battery you mentioned, is primarily due to the characteristics of the battery’s internal chemistry and the behavior of its components at different temperatures. Here’s why you observe variations in discharge current at different temperature ranges:

  1. 10-25°C Range (Optimal Operating Temperature):
    • The battery’s internal resistance is relatively low at temperatures within this range.
    • The electrolyte and electrode materials have good ion conductivity.
    • Consequently, the battery can discharge at a higher current, such as 3C or 7200mA in the case of your LP21700 4800mAh battery.
    • It operates optimally in terms of both capacity and discharge rate.
  1. 25-55°C Range (Elevated Temperature):
    • As the temperature increases, the battery’s internal resistance begins to rise.
    • The elevated temperature can accelerate certain chemical reactions within the battery, affecting its performance.
    • While the LP21700 battery can still deliver a relatively high discharge current (e.g., 2C or 4800mA), it may not perform as efficiently as it does within the optimal range.
    • Additionally, higher temperatures can lead to a slight reduction in battery capacity.
  1. -20-10°C Range (Low Temperature):
    • In cold temperatures, the internal resistance of the battery increases significantly.
    • The lower ion conductivity of the electrolyte and slower chemical reactions limit the battery’s ability to deliver a high discharge current.
    • In this range, the battery may only discharge at a reduced rate, such as 0.5C or 2400mA.
    • The reduction in capacity is more pronounced at lower temperatures, which means the total energy the battery can deliver is lower.

It’s important to note that lithium-ion batteries, like the LP21700, have an operating temperature range specified by the manufacturer. Operating outside this range can affect not only discharge performance but also the overall health and safety of the battery. Extreme temperatures can lead to reduced capacity, increased internal resistance, and, in some cases, permanent damage or safety hazards.

In summary, the discharge performance of a lithium-ion battery is significantly influenced by temperature. Operating the battery within its specified temperature range ensures optimal performance, while extreme temperatures can lead to reduced capacity and discharge current capabilities. Manufacturers design batteries to balance performance and safety under various conditions.
